Synthesis and characterization of Cu doped NiO nanoparticles (original) (raw)

Copper doped NiO nanoparticles were synthesized by chemical precipitation method and studied the structural, compositional, morphological, luminescence and optical properties using X-ray diffraction (XRD), Energy dispersive analysis of X-rays (EDAX), Scanning electron microscopy (SEM), PL Fluorimeter and High Resolution Raman spectroscopy. XRD studies confirm the fcc structure of the prepared samples. EDAX showed the effective doping of copper into NiO. For pure NiO, PL peak was observed at 434 nm and an enhancement in the PL intensity was observed with increasing dopant concentration. The Raman peak observed at 518 cm-1 confirms the Ni-O bonds and no impurity peaks were observed due to dopant.
